According to Plageman, the plan called for the 26-year-old inmate to use a weapon to kill a correctional officer, impersonate the officer while walking out of the jail, and collude with someone on the outside to be a getaway driver.

Information on the inmate's most recent failed escape plan was released in court Thursday morning. Ainsworth was not present in court because he posed a major security risk.

Ainsworth was convicted in January of 39 counts for his first escape attempt. During that incident, he escaped from Dominican Hospital, shot a deputy in the head with a Taser, and set off an intense 5-hour manhunt.

The Santa Cruz County District Attorney recommended a sentence of 189 years in prison, along with eight consecutive life sentences. Superior Court Judge Paul Burdick is scheduled to sentence Ainsworth on April 26.

An MRI machine is essentially a giant magnet, so Ainsworth's shackles had to be removed for the procedure.

Prosecutor Celia Rowland told the jury that Ainsworth began charting out his brazen escape plan after he had another MRI on his shoulder earlier that month, and realized he had to be unchained for the procedure.

When the 270-pound, 6-foot-7-inch inmate exited the MRI room, the five-foot 4-inch tall deputy began putting shackles on him. Suddenly, the inmate slugged the deputy in the head and bolted down Dominican Hospital's hallway toward an exit door. Bramanti sprinted after him. When they reached the parking lot, Ainsworth turned around, charged at the deputy and tackled her to the ground, Bramanti testified.

"He was punching me in my face, and I knew it was a matter of time before he knocked me out. If it was going to be my last day, I was going to go out fighting," Bramanti said while a tear rolled down her face. "He took my Taser and shot the Taser right into my head, point blank."

Ainsworth then stormed into Secret Garden Too preschool on Salisbury Drive and held a gun to a teacher's head, deputies said. There were 40 babies and toddlers in the classroom at the time, and no one was hurt.

More than 50 officers swarmed the area, and police found Ainsworth hiding in a house's upstairs bathroom on English Drive and he surrendered.
